Class SocketDynamicTableSource

java.lang.Object

org.apache.flink.table.examples.java.connectors.SocketDynamicTableSource

All Implemented Interfaces:

org.apache.flink.table.connector.source.DynamicTableSource, org.apache.flink.table.connector.source.ScanTableSource

public final class SocketDynamicTableSource
extends Object
implements org.apache.flink.table.connector.source.ScanTableSource

The SocketDynamicTableSource is used during planning.

In our example, we don't implement any of the available ability interfaces such as SupportsFilterPushDown or SupportsProjectionPushDown. Therefore, the main logic can be found in ScanTableSource.getScanRuntimeProvider(ScanContext) where we instantiate the required SourceFunction and its DeserializationSchema for runtime. Both instances are parameterized to return internal data structures (i.e. RowData).
